Description

  The present invention relates to a remote control signal receiving apparatus including an electronic device that can be remotely operated using a remote controller (remote control) and a control method thereof.

  Conventionally, remote controllers (hereinafter abbreviated as “remote controllers”) have been widely used in electronic devices such as televisions and videos, and home appliances such as air conditioners. As a format of a signal transmitted from the remote controller, there are a home appliance association format, an NEC format, a SONY format, and the like. All formats basically use Pulse Position Modulation (PPM) communication. The configuration of the most widely used NEC format is shown in FIG.

  The NEC format includes a leader code, a custom code (16 bits), a data code (16 bits), and a stop bit. Basically, only one custom code is assigned per manufacturer. The data code is data corresponding to the operation instruction content.

  With the increase in devices that can be remotely operated by a remote controller, it is desired to operate a plurality of devices with a single remote controller. A programmable remote controller is commercially available for such a demand. The programmable remote controller receives and stores a remote control code transmitted from a remote controller included with each device, and enables re-transmission. As a result, the functions of a plurality of remote controllers can be realized with a single remote controller.

  However, since such a programmable remote controller is expensive, there has been no example in which a programmable remote controller is adopted as a remote controller bundled with a device.

  In addition, a remote controller for a TV connection device such as a personal video recorder (hereinafter abbreviated as “PVR”) such as a DVD player, a DVD recorder, or an HDD recorder, which is used by being connected to a television (hereinafter abbreviated as “TV”). Many of them are equipped with TV control keys so that basic operations of the TV can be performed. In this case, the remote control codes of a plurality of TV manufacturers are preset in the remote control of the TV connection device so that it can be handled even if the manufacturer of the TV and the manufacturer of the TV connection device are different. The user can perform basic operation of the TV by operating the remote controller of the TV connection device and selecting the manufacturer code of the TV to be used.

  FIG. 8 is a diagram showing an example of the appearance of a PVR remote controller that can also operate a TV.

  The remote controller shown in FIG. 8 can be switched between TV and PVR operations by a slide switch 801. In recent years, many have a dedicated key for TV. As keys prepared for TV, a power key 802, an input switching key 803, a channel UP / DOWN key 804, and a volume UP / DOWN key 805 are generally used.

  If the PVR and TV are made by the same manufacturer, the custom code is the same. Therefore, in order to avoid cross-talk between models, it is common to use different data codes even if they have the same function in the PVR and TV, such as the power key 803 and the channel UP / DOWN key 804. General home appliance manufacturers and others produce and sell multiple electronic devices of different models, so they may have multiple custom codes. In any case, a plurality of devices can be switched and operated with one remote controller by using different remote control codes for the same function even for the same function (see FIG. 9).

Against this background, a technique for simplifying remote control operation has been proposed (see Patent Document 1). According to Patent Document 1, the TV main unit stores a remote control code for a specific operation of the TV connection device, so that when the TV connection device is operated, the TV also performs a predetermined operation in conjunction with the operation. is there. As a result, for example, it is possible to realize a function of automatically switching TV input when a PVR playback operation is performed.
JP 2002-320108 A

  However, when the TV manufacturer code is selected by the remote controller of the TV connection device, the user selects a desired manufacturer from among the manufacturer codes prepared for the TV connection device. The number and type of manufacturer codes to be prepared vary depending on the manufacturer of the TV connection device, and it is difficult for the user to determine. In addition, maker codes are generally prepared for TV connection devices for TVs of major domestic manufacturers, but remote control codes are installed on TV connection devices owned by users for TVs of emerging manufacturers. There is a problem that it cannot be operated.

  Therefore, as a simpler means for solving the above-described problem, it is conceivable that the television main body can discriminate a plurality of manufacturers' remote control codes in advance. By doing so, it becomes possible for the user to operate the TV with the remote controller of the TV connected device without selecting the manufacturer or registering while confirming the operation manual.

  Note that the technique described in the above-described patent document sets an operation on the TV side corresponding to a remote control code related to a specific operation of the TV connection device. This setting aims to simplify the user's operation procedure in a certain operation. Therefore, it is possible to reduce the number of operations that are performed each time, such as switching the input of the TV when reproducing the video stored in the PVR. However, in the technique described in this patent document, it is still necessary for the user to set an operation corresponding to the remote control code on the TV, and the point that the user is requested to work is not improved.

  As described above, since the television main body can discriminate the remote control codes of a plurality of manufacturers in advance, it is not necessary to require the user to perform a special operation of specifying the remote control code or setting the operation. However, there is a further problem due to the fact that the television main body can distinguish the remote control codes of a plurality of manufacturers in advance. This problem is that, in stores and showrooms in which multiple TVs that can discriminate remote control codes from multiple manufacturers are arranged in advance, devices other than the devices that are operated by the operator who operates the remote control operate. That's it. For example, it is assumed that a television set of company A and a television set of company B are arranged in the store, and the television set of company A can discriminate the remote control code of company B and accept channel switching and volume adjustment. When the user operates the remote control of the B company TV in order to operate the B company TV, the A company TV receives the remote control code. As a result, not only the TV of company B but also the TV of company A switches channels or changes the volume. When the television that is not operated by the user operates, the user may misunderstand that the television of company A is malfunctioning.

  Therefore, the present invention prevents a device that is not an operation target from malfunctioning even in an environment where a plurality of devices that can be operated by a remote controller are arranged, and the remote control of the TV connection device can be operated from the remote controller of the TV connection device without performing a special setting operation.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[First Embodiment]
FIG. 1 is a block diagram showing a configuration of a remote control signal receiving apparatus according to the first embodiment of the present invention.

  In FIG. 1, a television broadcast receiving apparatus (hereinafter simply referred to as “TV”) 101 which is a remote control signal receiving apparatus includes a light receiving unit 102, a memory 103, and a microcomputer (CPU) 104. The microcomputer 104 is connected to the light receiving unit 102 and the memory 103. In addition to the control program executed by the microcomputer, the memory 103 stores a remote control code for other companies described later. In the present embodiment, only components that operate by receiving a remote control signal (control signal) will be described, and descriptions of other components will be omitted.

  The remote controller 107 is an infrared remote controller (hereinafter abbreviated as “remote controller”) for remotely operating the TV 101. The remote control 107 includes a remote control input unit 108, a remote control microcomputer (CPU) 109 connected to the remote control input unit 108, and a remote control light emitting unit 110 connected to the remote control microcomputer 109.

  The remote control input unit 108 accepts key input by the user. Then, the first remote control microcomputer 109 issues a remote control code (remote control signal) corresponding to the key to the first remote control light emitting unit 110. The first remote control light emitting unit 110 converts each issued remote control code into an infrared signal (remote control signal) and outputs it.

  In addition, although the remote controller in this embodiment is set as the structure which transmits a control signal from a remote by infrared rays, the remote controller of this invention is not limited to infrared transmission.

  The TV 101 receives the remote control signal output from the remote control 107 and operates in accordance with an instruction corresponding to the remote control signal. The light receiving unit 102 receives a remote control signal from the remote control 107 and converts it into an electrical signal. The microcomputer 104 decodes the electric signal into a remote control code, and determines whether or not the signal can be processed. The memory 103 stores a control content signal corresponding to the remote control code, and the microcomputer 104 acquires the control content corresponding to the remote control code and performs a predetermined control process. For example, when the instruction input from the remote controller 107 is a channel switching instruction, control for demodulating a channel specified by a tuner (not shown) is performed. If the instruction input from the remote controller 107 is a volume adjustment instruction, control for adjusting the volume is performed on an amplifier (not shown). Although details will be described later, in addition to the remote control code specific to the TV 101 or the manufacturer of the TV 101, the memory 103 stores a remote control code for another company's TV and control information corresponding to the remote control code. Specifically, a code (custom code) assigned to a product or a manufacturer included in the remote control code and a plurality of data codes corresponding to the custom code are stored. Each data code is associated with a control instruction content (control information) for executing control instructed by the data code.

  Next, the operation in an environment in which the TV 101 and the remote controller 107 shown in FIG.

  FIG. 2 is a diagram illustrating an example of an environment in which a system including the TV 101 in FIG. 1 and other devices are adjacent to each other.

  FIG. 2 shows a TV 101 of company A and a remote control 107 (first remote control) corresponding to the TV 101, a PVR (DVD) 201 of company B and a second remote control 111 corresponding to the PVR, and a TV 202 of company C. A third remote controller 203 corresponding to the TV 202 is shown. Here, it is assumed that the TV 101 of company A, the PVR 201 of company B, and the TV 202 of company C are installed adjacent to each other. The PVR 201 is a DVD recorder, but is shown as a representative example of a device that can be connected to a TV, and may be a hard disk recorder, a VHS video deck, or the like.

  The second remote controller 111 is a remote controller for operating the PVR 201 of company B, but can also perform basic operations on the TV 202. This basic operation includes power ON / OFF, external input switching, channel UP / DOWN, volume UP / DOWN, and the like.

  S21 to S24 indicate remote control signals output from the illustrated remote controllers 107, 111, and 203, respectively. The signal S21 is a remote control signal unique to the company A including the custom code of the company A, and is a signal for operating the TV 101 of the company A. The signal S22 is a remote control signal including a custom code unique to the B company, and is a signal for operating the PVR 201 of the B company. The signal S23 is a remote control signal including a custom code unique to the C company, and is a signal for operating the TV 202 of the C company. The signal S24 is a signal for performing a basic operation of the TV 202. In this embodiment, it is assumed that all signals are configured in the above-mentioned NEC signal format (see FIG. 7).

  In the second remote controller 111, the user can set the TV manufacturer to be operated. In this embodiment, the TV manufacturer setting is set to the TV 202 of the company C. That is, the second remote controller 111 can turn on / off the TV 202 of company C and switch channels.

  Further, the memory 103 in the TV 101 of Company A stores remote control codes from a plurality of manufacturers. That is, in addition to the remote control code unique to company A, a remote control code unique to company B or C is stored. As described in the background art, it is now common to store a remote control code for operating the television of A company in a remote control device of a manufacturer other than A company. Then, based on the user's setting work, the remote control device of the company A is transmitted from the remote control device of another company, and the TV operation of the company A is performed. That is, by sending a remote control code for company C for operating the TV 202 of company C from the second remote controller 111, the TV 202 of company C can be operated from the remote control device of company B.

  However, in the case of a television set made by a manufacturer that does not have its own remote control code set in advance on another company's remote control device, the other company's remote control device cannot operate its own television. Therefore, the user must use the remote control device properly, which is very inconvenient.

  Therefore, the television 101 in this embodiment stores a remote control code for another company for operating another company's television. Then, the control unit (microcomputer 104) of the television 101 receives a remote control code for another company (for example, a remote control code for turning on a TV manufactured by B company) sent from a remote control device of another company, and the code is “power ON”. When it is determined that there is, control for turning on the power of the television is executed. In general, since the TV operations that can be performed by the second remote controller 111 are basic operations such as power ON / OFF, channel switching, and volume adjustment, remote control codes and control information of a plurality of manufacturers are provided on the TV of company A. A large amount of memory is not required for storage. With the above configuration, even if the remote control device of the other company does not store the remote control code of the company in advance, it is possible to operate the TV of the company from the remote control of the other company.

  However, as shown in FIG. 2, in the environment where the TV 101 manufactured by the company A and the TV 202 manufactured by the company C are arranged, the TV 101 manufactured by the company A reacts to the signal S23 for operating the TV manufactured by the company C. This may cause confusion in operation. However, the environment in which TVs are arranged as shown in FIG. 2 is limited to stores and showrooms, and TVs are rarely arranged side by side in homes that users actually use.

  Therefore, the TV 101 is configured to accept only the signal S21 of the remote control 107 manufactured by Company A at the time of shipment. Then, when the user performs predetermined setting work (for example, regional setting, channel setting, telephone line setting, personal information setting, etc.) that is almost essential after the purchase of the TV 101, the TV 101 performs a remote control of another company (for example, a second remote control). 111) so that a remote control signal for operating a television manufactured by another company is also received. As a result, it is possible to prevent an erroneous operation at a storefront or a showroom, and the user can use a TV operation key provided on a remote control device bundled with a TV connection device such as a PVR without any special setting work. It can be used effectively. The predetermined setting work may be any setting as long as the setting is performed after purchasing the TV. However, in order to surely obtain the effects of the present invention, it is desirable that the setting work is always performed at the user's home after purchasing the TV.

  Next, remote control code discrimination processing for discriminating remote control codes from a plurality of manufacturers will be described.

  FIG. 3 is a flowchart showing remote control code determination processing in TV 101 manufactured by Company A in FIG. This process is a process executed by the microcomputer 104 based on the control program read from the memory 103.

  In FIG. 3, when the microcomputer 104 detects a reader code indicating that the signal converted from the infrared signal to the electrical signal by the light receiving unit 102 is a remote control signal (YES in step S301), the microcomputer 104 uses the signal to create a custom code of company A. It is determined whether or not a code has been detected (step S302). This determination process can be performed by comparing with a custom code stored in the memory 103 in advance. If it is determined that the custom code is from company A, the process proceeds to step S303. If it is determined that the custom code is different from the custom code of company A, the process proceeds to step S306.

  In step S303, the microcomputer 104 determines whether a valid data code is detected from the received remote control signal. As a result of this determination, when a valid data code is detected, the process proceeds to step S304. In step S304, the detected data code is analyzed. The processing of step S303 and step S304 adds the received data code to the data code group stored in the memory 103, and if there is a matching data code, the control contents previously stored corresponding to the data code are displayed. This is the process to identify. Thereafter, in step S305, an operation based on the instruction specified in step S304 is executed. For example, if it is determined that the operation is related to volume increase as a result of analyzing the data code, a volume increase command is issued to an amplifier (not shown) and other related functional units.

  When the TV 101 is displayed at a storefront or a showroom, the processing is usually performed in this series of flows. Therefore, the TV 101 does not operate with a remote control code other than Company A.

  On the other hand, if it is determined in step S302 that the custom code is different from the custom code of company A, the process proceeds to step S306, and the microcomputer 104 determines whether or not a predetermined setting is performed. As a result, if the predetermined setting has not been performed, nothing is performed and the process returns to step S301. That is, the input remote control code is discarded. Thus, even in an environment where TVs of a plurality of manufacturers including the TV 101 are arranged, unless a predetermined setting is made on the TV 101, it does not respond to a remote control operation by a remote controller other than the company A.

  As a result of the determination in step S306, when it is determined that the predetermined setting has been performed, the process proceeds to step S307. In step S307, the microcomputer 104 determines whether or not the received custom code other than the company A is valid (step S307). Here, a plurality of custom codes other than the company A are stored in the memory 103 in advance, and the TV corresponds to the received custom codes other than the company A by the microcomputer 104 referring to the plurality of custom codes. Determine whether or not.

  As a result of the determination in step S307, if the television 101 corresponds to the received custom code other than company A, in step S308, the microcomputer 104 determines whether or not the data code in the received remote control signal is a valid data code. To do. Here, it is determined whether or not the data code of the received remote control signal matches the data code group corresponding to the custom code specified in step S307. If there is a matching data code, the process proceeds to step S308. In step S <b> 308, the microcomputer 104 acquires control information corresponding to the data code from the memory 103. Thereafter, the process proceeds to step S305, and the process of step S305 described above is executed.

  According to the first embodiment, when a custom code other than the company A is detected from the remote control signal received from the remote controller, the TV 101 determines whether or not a predetermined setting has been performed. If the predetermined setting has not been performed, the remote control signal is ignored. If the predetermined setting has been performed, the operation corresponding to the remote control signal is performed even if the remote control signal is from a company other than Company A. Thereby, even in an environment where a plurality of TVs and TV connection devices of each manufacturer that can be operated by a remote controller are arranged, it is possible to prevent a TV or the like that is not operated by the user from operating. In addition, it is possible to perform an operation using a remote control signal for another manufacturer by using a predetermined setting of the TV 101 performed after installation of the user's house as a trigger, thereby improving user convenience.

[Second Embodiment]
The remote control signal receiving apparatus according to the second embodiment of the present invention has the same configuration (FIG. 1) as that of the remote control signal receiving apparatus according to the first embodiment. About the same part, the same code | symbol is attached | subjected and the description is abbreviate | omitted. Only differences from the first embodiment will be described below.

  In the first embodiment, in order to receive a remote control signal from another company and enable the operation, a setting that is almost essential when the television is installed is used as a trigger. In other words, it did not require a dedicated setting work for enabling reception of remote control signals from other companies. On the other hand, in the second embodiment, a menu selection method is adopted as a setting method for enabling the company's own television to operate with a remote control signal for operating another company's television.

  FIG. 4 is a diagram showing an example of a received remote control code selection screen displayed by the remote control signal receiving apparatus according to the second embodiment of the present invention. This screen is generated and displayed based on the control of the microcomputer 104 of the TV 101.

  In FIG. 4, on the reception remote control code selection screen 400, the remote control code reception for the A company and the C company is ON. That is, the selection screen 400 is a screen for setting whether to execute control based on a manufacturer-specific remote control signal stored in the memory 103. In this state, a remote control code including custom codes of company A and company C is received, and control corresponding to the data code can be performed. Also in this embodiment, as in the first embodiment described above, at the time of product shipment, control corresponding to only the remote control code of the company (here, Company A) is possible. As a result, at the store, the TV does not react inadvertently to a remote control operation by a remote controller of another manufacturer. Information set on the selection screen 400 is stored in the memory 103 and used for control described later.

  In addition, remote control codes of manufacturers other than Company A can handle only basic operations on the TV.

  FIG. 5 is a flowchart showing a remote control code determination process executed by the remote control signal receiving apparatus according to the second embodiment of the present invention. This process is a process executed by the microcomputer 104 based on the control program read from the memory 103.

  In FIG. 5, when the microcomputer 104 detects a leader code from the remote control signal converted into an electrical signal by the light receiving unit 102 in step S501, the microcomputer 104 proceeds to step S502. In step S502, it is determined whether a custom code of company A is detected from the signal. Here, the TV 101 accepts only the custom code of company A, which is the company, at the time of shipment.

  When the microcomputer 104 detects the custom code of company A, the microcomputer 104 proceeds to step S503. In step S503, it is determined whether a valid data code is detected from the remote control signal (step S503). Since this determination process is the same as the process in step S303 in the first embodiment described above, detailed description thereof is omitted.

  As a result of the determination in step S503, when a valid data code is detected, the process proceeds to step S504. In step S504, the detected data code is analyzed. The analysis process for analyzing the data code is the same as the process executed in step S304. Thereafter, the process proceeds to step S505, and operation processing for an operation such as power ON / OFF is performed based on the analysis result in step S504. When the TV 101 is displayed at a storefront or a showroom, processing is usually performed in this series of flows.

  On the other hand, when a custom code other than the company A is received and the custom code of the company A cannot be detected in step S502, the process proceeds to step S506. In step S <b> 506, the microcomputer 104 confirms the reception setting state of the remote control code selected (set) on the reception remote control code selection screen 400 of FIG. 4 using the setting information stored in the memory 103. That is, it is specified which manufacturer the detected custom code belongs to. Further, it is determined whether or not the manufacturer's reception setting corresponding to the specified custom code is ON. If the result of this determination is that the manufacturer is compatible but the reception setting is OFF or the custom code is not compatible, the process returns to step S501.

  On the other hand, if the received setting of the custom code other than the company A is ON, in step S507, the microcomputer 104 determines whether or not the data code in the received remote control signal is a valid data code. Since this process is the same as the control in step S308 in the first embodiment described above, a description thereof will be omitted. If the result of determination in step S507 is a valid data code, the microcomputer 104 analyzes the data code. Since this process is the same as the control in step S309 in the first embodiment described above, a description thereof will be omitted. Thereafter, the process proceeds to step S505.

  As described above, according to the second embodiment, the TV 101 is set to receive a remote control code of a desired other company on the reception remote control mode selection screen 400 in advance. When a custom code other than Company A is received, the custom code of the manufacturer whose reception setting is ON based on the reception setting state of the remote control code selected (set) on the reception remote control code selection screen 400 Only accept. Thereby, even in an environment where a plurality of TVs and TV connection devices of each manufacturer that can be operated by a remote controller are arranged, it is possible to prevent a TV or the like that is not operated by the user from operating. In addition, the remote control operation of another manufacturer can be performed with a simple setting on the reception remote control code selection screen 400 on the TV 101, and the convenience of the user can be improved.

[Third Embodiment]
The remote control signal receiving apparatus according to the third embodiment of the present invention has the same configuration (FIG. 1) as the remote control signal receiving apparatus according to the first embodiment. About the same part, the same code | symbol is attached | subjected and the description is abbreviate | omitted. Only differences from the first embodiment will be described below.

  In the third embodiment, a setting control method using a specific key is adopted as a setting method for discriminating remote control codes of a plurality of other manufacturers.

  FIG. 6 is a flowchart showing a remote control code determination process executed by the remote control signal receiving apparatus according to the third embodiment of the present invention. This process indicates a remote control signal reception operation when the TV 101 is turned off. This process is a process executed by the microcomputer 104 based on the control program read from the memory 103.

  In FIG. 6, when the microcomputer 104 detects a reader code from the remote control signal converted into an electrical signal by the light receiving unit 102 (step S601), it determines whether or not a custom code of company A has been detected (step S602).

  When the microcomputer 104 detects the custom code of the company A, the microcomputer 104 determines whether the data code in the signal from which the custom code of the company A is detected corresponds to the power key of the company A TV (step S603). As a result, if the data code corresponds to the power key of the company A TV, the process proceeds to step S604, and the microcomputer 104 performs a power ON process of the TV 101. When the power of the TV 101 is turned on in the series of flows, the process proceeds to step S605. In step S605, the control is changed so that the microcomputer 104 accepts only the remote control signal including the A company custom code. In other words, it can be operated only by the remote control device of company A.

  On the other hand, if it is determined in step 602 that a custom code other than company A has been received and the custom code of company A has not been detected, the process proceeds to step S606. The microcomputer 104 sequentially detects custom codes of manufacturers other than the company A registered in advance. Although FIG. 6 shows an example in which custom code detection of company B and company C is executed as step S606 and step S610, it is not limited to this. If it does not match all the registered custom codes, no processing is performed and a transition is made to the next remote control signal reception waiting state.

  If the custom code of company B is detected as a result of the determination in step S606, it is determined whether or not the data code in the signal from which the custom code of company B is detected corresponds to the power key of the TV of company B (step S606). S607). As a result, if the data code corresponds to the power key of the B company TV, the microcomputer 104 performs a power ON process for the TV 101 (step S608). When the power source of the TV 101 is turned on in these series of flows, the microcomputer 104 thereafter changes the control so as to accept only the remote control signal including the custom codes of the A company and the B company. That is, it becomes a state which can be operated only with the remote control device of company A and company B.

  Similarly, when the custom code of company C is detected in step S610, the process proceeds to step S611, and whether or not the data code in the signal in which the custom code of company C is detected corresponds to the power key of TV of company C. Is determined. As a result, when the data code corresponds to the power key of the C company TV, the microcomputer 104 performs the power ON process of the TV 101 (step S612). When the power of the TV 101 is turned on in these series of flows, the microcomputer 104 thereafter changes the control so as to accept only the remote control signal including the custom codes of the A company and the C company. That is, it becomes a state which can be operated only with the remote control device of company A and company B.

  Since each command waiting state in steps S605, 609, and 613 is independent of the process shown in FIG. 6, even if a remote control signal corresponding to a power key of a non-target manufacturer is sent, the TV 101 Does nothing and ignores it.

  In steps S605, 609, and 613, it is possible to determine the data code corresponding to the manufacturer's custom code that has been turned on in accordance with the processing shown in FIG. That is, when the power of the TV 101 is turned off and the remote controller is turned on, the remote controller codes of a plurality of manufacturers are discriminated. On the other hand, when a power-off operation is performed by the remote controller while the TV 101 is turned on, a restriction is placed on the remote-control code to be determined.

  According to the third embodiment, when the power source of the TV 101 of the company A is turned on by the remote control 107 of the company A, it is possible to prevent the remote control signal from the remote controller of another manufacturer from being accepted. As a result, even in an environment where a plurality of TVs and TV connection devices of each manufacturer that can be operated by a remote controller are arranged, it is possible to prevent a TV or the like that is not the operation target of the user from operating.

  For example, when the TV 101 of company A is turned on with the remote control of the TV connection device of company B, the TV 101 can be operated with the remote control of the TV connection device, and the trouble of changing the remote control can be saved. Become. As a result, user convenience can be improved.

  In the above embodiment, the case where the power key is used in order not to give a special operation feeling to the user who is an operator has been described. However, the present invention is not limited to the power key, and can be realized by providing a specific key for operation switching. For example, it may be possible to switch to the custom code discrimination mode of the remote controller by pressing the input switching key for a predetermined time or longer.
